FEEDING APPARATUS.

Application filed October 14, 1925. Serial No. 62,407.

My invention relates to feeding apparatus and particularly to apparatus for feeding cloth or other flexible material to rolls or the equivalent adapted to squeeze moisture from the cloth or other material, or adapted to treat them in some other manner.

My invention has among its other objects the production of apparatus of the kind described which is simple in construction, compact, convenient, durable and satisfactory for use wherever found applicable. I

A particular object of the invention is to provide improved means for feeding cloth and the like to rolls adapted to remove water therefrom so that the hands of the operator need not be brought into close proximity to the rolls and so that the cloth or other mate rial may be introduced between the rolls with a minimum of effort on the part of the op erator.

One form of the invention is embodied in apparatus for feeding wet or moist clothes or other articles to the rolls of a clothes wringer. The improved apparatus preferably comprises a lever having one of its ends pivoted to the frame of the wringer and having a feeding member pivoted to its other end. The lever is provided with a handle disposed intermediate itsfends and is adapted to be mountedon either sideofthe wringer. The feeding member is preferably formed with two converging concave surfaces conforming to the cylindrical surfaces of the rolls so that the rolls will not tend to draw the feeding member through them. The concave surfaces also insure that the rolls will quickly withdraw the clothes or other articles from the feeding member when the feeding member is moved into close proximity. to the rolls. An advantage of pivoting the feeding member to the lever is that the feeding member automatically adjusts itself to present the clothes or other articles to the rolls in a proper manner. Means is preferably provided for limiting the angular movement of the feeding member relative to the lever.

Many other objects and advantages of the construction herein shown and described will be obvious to those skilled in the art from the disclosure herein given.

To this end my invention consists in the novel construct-ion, arrangement andcombination of parts herein shown and described, and more particularly pointed out in the claims.

Referring for the present to Figs. 1 to 3,

I ction taken on line 55 of inclusive, the reference character 10 designates generally a clothes wringer which may be of any desired construction. In this instance, the clothes wringer 10 comprises side posts or standards 11 in which rolls 13 and 14 are rotatably journalcd, the rolls 13 and 14 being adapted tovremove water from clothes or other articles passing through the Wrmger. Any suitable means may be provided Ior driving the rolls 13 and 14, as, for

instance, a shaft 15 operativclyconnected to an electric motor (not shown) or the like, the shaft 15 being operatively connected to the rolls 13 and 14 by suitable gearing (not shown);

My invention is limited to the above described details of construction only to the extent defined in the appended claims.

Improved means is provided for feeding wet clothes or other articles to the rolls 13 and 14, the means preferably comprising a lever 17 pivotally and detachably mounted upon the wringer 10. Thus, a pin 18 preferably PlOjGClJS from one end of the lever'17 and is journaled in one of a pair of lugs 19 projecting from the posts or standards 11. It will be noted that the lugs 19 are disposed upon opposite sides of the wringer so that the im proved feedingmeans may be transferred from one side of the wringer to the other side thereof.

Pivotally secured to the freeend of the lever 17 by a shouldered screw 21, or the equivalent, is a feeding member 23 having a substantially straight feeding edge 24 arranged to enter between the rolls 13 and 14. The

feeding member 23 is preferably formed with two converging concave surfaces 26 and 27 meeting substantially along the edge 24. As best shown in Figs. 3 and 4, the cancave surfaces 26 and 27 conform substantially to the cylindrical surfaces of the rolls 13 and 14. This construction insures that the feeding edge 24 Will not be drawn through the rolls 13 and 14 and that the rolls 13 and 14 will quickly withdraw clothes or the like presented to the rolls by the feeding member, it being obvious that the rolls 13 and 14 cannot bind upon the concave surfaces 23 and 24.

I Referring now to Figs. 5, 6 and 7, a lug 30 formed integral with the feeding member 23 projects into a slot 31 formed in the lever 17.

- The lug 30 and the slot 31 cooperate to limit angular displacement of the feeding member 23 relative to the lever 17. This prevents the feeding member 23 from assuming an unclesirable angle with respect to the rolls 13 and 14. However, the feeding member 23 may move through a predetermined angle around the shouldered screw 21 so that it may adjust itself to the varying thickness of the clothes or other articles fed to the wringer. It will be readily understood that when the feeding member is advanced to the rolls 13 and 14, its feeding edge 24 will tend to assume a position parallel to the axes of the rolls 13 and 14. An advantage of this construction is that if the clothes or other articles are being presented to the rolls 13 and 14 by the feeding member 23 and the clothes or other articles are draped over one end of the feeding member, the feed ing member will quickly adjust itself, and be brought into cont-act with the rolls to introduce the clothes or other articles between the rolls.

The lever 17 is preferably provided with an integral handle 33 disposed in back of and intermediate the pin 18 and the shouldered screw 21. This enables the attendant to readily operate the improved apparatus by means of the lefthand while using the right hand to drape the clothes or other articles over the feeding member 23. In other words, the attendant may quickly and easily drape the clothes or other articles over the feeding member 23 without removing the left hand from the handle 33 or without passing the clothes over the left hand.

The operation of the above described apparatus is substantially as follows: After the wringer 10 has been set in operation, the attendant grasps the handle 33 with the left hand and moves the lever 17 and the feeding member 23 into a position approximating that in which the handle and feeding member are shown in dotted lines in Fig. 2. One end of an article which is to be introduced between the rolls 13 and 14 is then draped or hung over the member 23, as indicated by dotted lines in Fig. 4. The feeding member 23 is then advanced toward the rolls 13 and 14 unti the rolls draw the article between them. The feeding member 23 is then retracted to receive the next article which is to be fed to the rolls.

As hereinbefore set forth, the improved apparatus may be used upon either side of the wringer 10. Thus, it may be removed from the position wherein it is shown in Fig. 2 and mounted upon the other side of the wringer, the pin 18 being then inserted in the lug 19 provided upon the other side.

' Having thus described my invention, it is obvious that various immaterial modifications may be made in the same without departing from the spirit of my invention; hence I do not wish to be understood as limiting myself to the exact form, construction, arrangement and combination of parts herein shown and described, or uses mentioned.
